[Mod] Snow Biomes [3.2] [snow]

[ak399g]

Grabbed the new snow mod. Got this error partway through the game and it crashed:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

ok thanks, fixed in git: https://github.com/Splizard/minetest-mod-snow/archive/master.zip
If it happens again or regularly ill release a new version.

now melting and freezing included in core, no need in this abms if liquid_finite and weather is true
479 --Melting
512 --Freezing

[paramat]

Yes indeed, so there could be small positive and negative random amounts added to velocity and acceleration (i will do this in my snowdrift mod), but the average acceleration will be zero.

Splizard, something i'm doing in my snowdrift mod is setting snow velocity = {x=0, y=-1, z=-1}, this makes the snow drift southwards as it falls a little slower than the cloud drift and constant North wind. The effect is beautiful.

[Mito551]

why not use default:snow nodes?

[paramat]

Found some reliable data for drizzle, rain, hail and snow terminal velocities, i had been using 1 metre per second for snow ...
"Snow flakes of any size falls at about 1 m/s, slightly faster aloft because of the density correction [exp(z/20)]. The fallspeed of snow increases only slightly with snow flake size is because of the intricate shape of snow : the surface area of a growing crystal increases about as rapidly as its weight."

Splizard: okay. As soon as this mod supports using default snow/ice nodes instead of custom ones, I think I'll be adding it to my server (ditto for the snowdrift/light snow mod).

Might as well make use of the default nodes. No need to make duplicates.

479 --Melting
512 --Freezing

But that only works of finite liquid is enabled and weather is on :/ I might add a check for this.

@paramat
Thanks for your research on falling snow.

@VannesaE, Hybrid Dog, Inocudom and Mito551
Fine, fine :P I'll redefine the default snow nodes for version 2.0, I can't yet because 0.4.7 has no support for leveled nodes and theres the problem of backwards compatibility. Default does not even use snow anyway! But no problem, ill figure it out.

[proller]

enabling melting with old liquid will cause water disaster.
and enabling freezing without melting will make fully frozen world after some time.

why not just leave the biome static?

[GreenGerm]

sorry i dont have that. Im running the windows version

ok sorry, Im not sure how to use it on windows :/

Could you email me a copy of minetestmapper.py? I've got a little expreience with python and I might be able to make a version for windows.

Minetest_mapper has already been written for Windows in C++

Sometimes, when generating land chunks, the snow biome will render in place of a forest. It renders perfectly except for the fact that dozens of apples still spawn, with no trees to be attached.

Is there an option for using the old version of snowfall?

Yes that is a bug, I'll fix that. No there's not though you can use Light snow for snow mod though.

[ak399g]

I'm only asking because the new snowfall (rapid images) causes much lag/drop in framerate, but I do still want it to snow. Just not the way it does.

[paramat]

The light snow mod linked to is designed to be much less processing-intensive and you can also adjust the heaviness of the snowfall.

[ak399g]

Seems alright for now. Thanks.

[Splizard]

New release in time for christmas!
http://ubuntuone.com/7Rkg5Muq1rnZl9o9zVLrs3 (Version 2.0)

Snow mod now uses the default namespace for snow, ice, etc. as requested.

New release has sleds and a bonus christmas skin!

[Temperest]

Wow, now that is truly impressive!

[paramat]

This mod has always been one of my 2 essential mods, the other is worldedit.
I have always found the default biome perlin 'scale' or 'spread' of 150 nodes too small, and personally use 256 nodes to be close to the 250 node spread of the default perlin noise that defines deserts and normal biomes.
Ideally also you could use that noise to place snow biomes away from deserts, making that noise essentially temperature:
noise < -0.4 snow
noise > 0.4 desert

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

local perl1 = {
    SEED1 = 9130, -- Values are minetest mapgen V6 desert noise.
    OCTA1 = 3,
    PERS1 = 0.5,
    SCAL1 = 250,
}

I DL'd this one and OoChainLynxoO's candy cane mod for a nice wintery combination :)

[LazyJ]

Howdy :)

I'm having some trouble with the 2.0 version of Snow Biomes creating snow biomes in all newly genererated surface areas of the map except deserts. The result is a world of only snow biomes, snow-covered jungle biomes, and desert biomes.

This doesn't happen when I use the 2013_09_03 release of the Snow Biomes

I'm testing Snow Biomes 2.0 in Minetest 0.4.8, 2013_12_09 unstable build, compiled on Linux from Github source code, with only the default, minetest_game mods in new test worlds.

Thanks for a great mod!

Oh thanks for reporting that! Please redownload the 2.0 version of the mod It should be fixed.

[LazyJ]

Howdy :)

I downloaded the mod again and now Snow Biomes 2.0 doesn't take over the whole mapgen.

Just an idea. Now that we've had a taste of a total arctic world, do you think you could make that bug into a config setting to toggle it on and off and make it so even deserts are covered with snow too? Combining this bug with HybridDog's WinterTP texture pack to create an entirely arctic world.

Thanks for the quick fix. ;)

2013_12_12 ps.
I just thought of another request. What needs to be changed or added to the code to make the snow biomes only appear at a minimum altitude of y60 (or whatever altitude players chose). I'd like to have snow capped mountains.

[Sokomine]

Is there any way yet to use it in combination with the undergrowth and dryplants mods? Whenever I enable the snow mod, I get hardly any advanced nature nodes. A single horizontal tree or an invividual root here and there might be all of that mod.

The snow itshelf got a bit strange as well. Those individual overlarge snowflakes where pretty ok. The current way of localized snowstorms is rather odd.

This is already in the config file (have a look in the mod folder, config.txt).

A quick fix I can think of is to add undergrowth and dryplants to a file called depends.txt in Snow mod's folder.

[Dopium]

Great mod but it seems to conflict with default flowers, in other words no flowers generate when using this mod.

Thanks! Adding those mods/mods from the modpack to snow's depends.txt helped. Now there's snow and rich plantlife. At least there's a snowy christmas in MT now :-)
